All surfaces to be coated shall be clean, dry and free of contaminants. Before coating, all surfaces shall be assessed and treated in accordance with ISO 8504:2000. Blast clean to Sa 2½, surface roughness 40–75 µm. Before rust removal, oil, weld spatter shall be removed and welds and sharp corners ground. If the film coated with this paint is mechanically damaged and localized rusting occurs, the area shall be spot blast cleaned to Sa 2½ or power tool cleaned to St 3 before localized repair of the primer. If chalking or zinc salts appear on the old film, the zinc salts and contaminants can be removed before applying the intermediate or topcoat.
1. During application, ensure adequate ventilation and exhaust, keep away from sources of ignition, and wear protective equipment such as masks and gloves; maintain adequate ventilation also during curing. 2. When mixing, first stir the base uniformly, then add the hardener according to the ratio and mix uniformly; adjust the thinner amount according to application needs and temperature changes, stir thoroughly and allow induction; filtering through a 120-mesh screen before use is recommended, and continue stirring during use. 3. Excessive thinner will reduce sag resistance; the thinner amount must never exceed environmental regulation limits. 4. This product is only suitable for application on blast-cleaned steel surfaces and approved epoxy zinc powder coatings and inorganic zinc silicate coating surfaces; it must not be applied over other types of coatings. Alkyd and alkyd-modified coatings must not be applied directly over this product. 5. During application and curing, the substrate temperature must be above 5 °C and at least 3 °C above the dew point, with relative humidity not exceeding 85%. 6. Cutting of structures coated with this paint will generate smoke and dust; take appropriate protection. 7. This product is not suitable for underwater use. 8. Avoid dry spray or over-application during application; applying the next coat over a "dry sprayed" coat may produce pinholes, and over-application prolongs curing, handling and recoating time. The coating thickness must match the surface roughness; low film thickness should not be applied on rough surfaces, and over-application should be avoided. 9. When work is interrupted, do not leave paint in the hose, spray gun or spray equipment. Flush all equipment thoroughly with thinner. If the interruption is too long, it is recommended to remix a new batch of paint for application. 10. All equipment shall be cleaned with thinner immediately after use. Flushing the spray equipment periodically during daily work is good practice. The cleaning frequency depends on spray volume, temperature, spraying time and interruptions. 11. Leftover paint and empty cans shall be disposed of according to local regulations.

1. For the coating and its recommended thinners, see the safety sheets and the safety data of the relevant materials. This is a solvent-borne coating; avoid inhaling spray mist and solvent vapours, and avoid exposing skin and eyes and contact with uncured paint as far as possible. 2. All work related to the application and use of this product must comply with the relevant national health, safety and environmental standards and regulations. 3. If welding or flame cutting is required on metal coated with this product, dust and fumes will be generated; use appropriate personal protective equipment and adequate local ventilation. 4. If in doubt about the suitability of this product, consult the company.
